Celeb chefs are huge opinion makers, and it’s not uncommon for them to spin that image to their advantage by releasing cookbooks or endorsing products. But critics are wondering when they should draw the line. For example, Anthony Bourdain was disgusted by Rachael Ray’s decision to plug Dunkin Donuts, a product not really known for its refined flavor (more of refined sugar).

The endorsement comes amid reports of increased juvenile diabetes, and in some people’s opinion, runs counter to TV chefs’ efforts to teach families to cook delicious, nutritious meals. Jamie Oliver, after all, actually went school cafeterias to think of non-greasy alternatives to the average school lunch.
